Objective

To use the DB component to run simple Insert and Select SQL statements on a Database.

Prerequisites

  • Start Fiorano Enterprise Server (FES) and Fiorano Peer Server (FPS)
  • Login to eStudio application
  • Understand the basic menus and perspectives (panels) in eStudio application
  • Before configuring the database, add the JDBC driver of the database as a resource to the JDBC System lib. Please Refer to the Add Resources to a Microservice section to perform this.

Scenario

  1. Configure a DB component to insert data into a table in a database using Insert Statement.
  2. Configure a DB component to fetch data, from the database that is used to insert data, using Select Statement.

Components used

Setting up the Example

The DB component is an all-encompassing powerful component which can be used to configure simple and nested queries like insert, update, delete and select. Following sections illustrate the steps to configure the component with Insert and Select query, which comes under the purview of this example, and thereby the steps to run the example as well.

Insert Query Event Process Configuration

The first step to create the Insert/Select example using DB is to configure the database. Perform the following actions to configure DB component with Insert query:

  1. Add a new Event Process with name 'DB_Insert_Eg'.
  2. Drag the DB component from DB category in the Service Palette to the Fiorano Orchestrator.


    Figure 1: Adding DB component to Fiorano Orchestrator

  3. Click the DB component and do any of the following to rename the component from 'DB1' to 'DB_Insert' to distinguish it from the DB component that gets configured for Select statement in 'Select Query Event Process Configuration' section:
    1. Press F2, change the name and click OK.


      Figure 2: Renaming using Keyboard action 'F2'
       
  4. Go to Name property under General tab in Properties, change the name and press ENTER.


    Figure 3: Renaming using General Properties

Configuring DB component

To configure the DB component, perform the following actions:

  1. Double-click the DB_Insert in the Orchestrator to open Configuration Property Sheet (CPS).
  2. Click the Database Configuration ellipsis button to open DbConfigurations Panel.

  3. Provide the following details in DbConfigurations Panel and click OK:
    1. Database: Oracle (Choose the database to be connected to. It is Oracle in this example)
    2. Driver: oracle.jdbc.driver.OracleDriver (Retain the default value)
    3. URL: jdbc:oracle:thin:@<SystemIP>:xe (in place of 'SystemIP', enter the machine IP in which the Oracle database is installed and 'xe' is the database name).
    4. User name: User name to connect to the database.
    5. Password: Password for the above user name.
    6. Named Configuration: OracleNamedConfig (Provide any value here to save the database configuration as Named Configuration to be used in future. 'OracleNamedConfig' is the name used in this example)
